This is a test of commonsense with single/multi-choices. Complete the next sentence:

How to tell if a girl likes you over text 
Pay attention to how often she starts the conversation. 
If initiating the conversation always falls on your shoulders, odds are, she is not very interested. On the other hand, if she starts the conversation too often, she might not be interested, either.

Possible answers:
 1). When a girl likes a guy, she will likely try to show her interest without being too obvious or looking too needy. As a result, she will start at least half of your conversations if not most, but probably won't start all of them..
 2). You could also notice her staring at your chest to see if you make eye contact or staring into the distance during a conversation. Checking in on her, even if you both know each other like the back of your hand, is an important thing to have in a girl..
 3). If you notice a lot of texting and face-to-face communication, but no one shares the same tastes about each other, a girl might like you. Watch out for basic concepts when you're talking to her..
 4). If you started the conversation spontaneously, or you ask her anything during the conversation, she might be. Periodically check in the girl's body language for the same signs you notice while texting..
The answer is:
1).
